Overlapping Syndromes: Drug-Induced Vasculitis From Hydralazine With Positive Antinuclear Antibodies.

Hydralazine is an antihypertensive medication that has been associated with drug-associated autoimmune syndromes like interstitial lung disease, pauci-immune glomerulonephritis, and hypocomplementemia. Hydralazine-induced ANCA-associated vasculitis and hydralazine induced positive antinuclear antibodies are rare. Clinical manifestations range from arthralgia, petechiae, or rash to multiorgan involvement. When presented as pulmonary-renal syndrome, it can be rapidly progressive and fatal. Here, we describe a case of hydralazine-associated vasculitis with rapidly progressive glomerulonephritis and highlight the importance of early diagnosis and prompt treatment.

Polypharmacy in a Patient With Intellectual and Developmental Disabilities.

Prader-Willi syndrome (PWS) is an uncommon condition and its clinical manifestation in adulthood includes central obesity, hypogonadism, osteoporosis, cardiovascular disease, diabetes mellitus, and sleep apnea. These patients often have mild to moderate intellectual disability and are dependent upon their caregiver for healthcare needs. Hence, they may be at increased risk of polypharmacy-related complications, if there is poor communication between healthcare providers and caregivers. We present a case of a 26-year-old adult with PWS and mild to moderate intellectual disability, who was found to have acute kidney injury resulting from drug interaction between multiple nephrotoxic medications. Our case report highlights the importance of continuity of care with primary care providers, especially in patients with intellectual and developmental disabilities (IDD).

Risk factors of stroke in Pakistan: a dedicated stroke clinic experience.

BACKGROUND: Secondary prevention of cerebrovascular disease through dedicated stroke clinics has been shown to decrease recurrent vascular events in patients. However, there is limited literature describing such stroke clinic experiences from low and middle income countries. This study describes patient characteristics and observations made at the first systematized stroke clinic in Pakistan. METHODS: A retrospective audit of medical records of all patients presenting between September 2006 and August 2008 with a cerebrovascular event was conducted. Information about clinical presentation, modifiable risk factors and laboratory and radiological investigations was collected. Burden of disability was assessed using Modified Rankin score. Data was entered and analyzed using SPSS 14.0. RESULTS: 159 patients with a mean age of 57.0 +/- 13.9 years were included in this study and 34.6% of all patients were women. 108 patients were diagnosed with ischemic stroke (67.9%) while 34 patients presented with hemorrhagic stroke (21.4%) and 17 patients presented with transient ischemic attacks (10.7%). Hypertension was the most common modifiable risk factor seen in 78.0%, followed by diabetes in 40.3% and dyslipidemia in 31.5%. At presentation to clinic, only 26.0% patients with dyslipidemia and 64.5% patients with hypertension were on appropriate medications. CONCLUSION: A high prevalence of modifiable risk factors such as hypertension in stroke patients was observed and it presents an opportunity for conventional interventions in Pakistan. Systematized clinics for stroke and an algorithmic approach in primary care towards stroke may improve the implementation of evidence based secondary prevention strategies in developing countries.

Knowledge, attitudes and practices regarding dengue fever among adults of high and low socioeconomic groups.

OBJECTIVE: To ascertain the knowledge, attitudes and practices of selected adult population in Pakistan regarding Dengue Fever. METHODS: A cross sectional survey was conducted among selected communities with different socio-economic backgrounds in Karachi, Pakistan. A sample size of 440 adults (aged 18 years and above) were interviewed using a pre-tested questionnaire regarding their knowledge, attitude and practices about dengue fever. A composite scoring system, based on the answers given in the questionnaire, was used to establish the level of awareness in the population. The division of the higher and lower socio-economic groups was based on their income and locality; both these variables were determined as a part of our survey. RESULTS: Data from 400 respondents (244 males, 156 females) was used for primary analysis. About thirty five percent of the sample had adequate knowledge about dengue fever and its vector. Knowledge had significant associations with education (p = 0.004) and socioeconomic status (p = 0.02). The high socioeconomic group showed better preventive practices. CONCLUSION: Knowledge of dengue is inadequate in the low socioeconomic class. Better preventive practices against the vector are prevalent in the high socioeconomic group. Hence, a greater focus should be accorded to the low socioeconomic areas in future health campaigns.
